SPECIFICATION forming part of Letters Patent No. 376,998, dated January 24, 1888. I

I Application filed July 1, 1887. Serial No. 43,080. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM H. WALKER,

a citiaen of the United States, residing at Milford, In the county of New Haven and State of Gonnecticut,haveinvented certain new and useful Improvements in Dies for Making'Hames;

, and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon,w hich form a part of this specification.

In said drawings, Figures 1 and 2represent' plan views of a top and bottom die, respectwork more perfectly andwith less labor than heretofore. I

The dies comprise two setsonefor forming and clinching and the other for the welding process. The first comprises a bottom die, Fig. 5, having recesses a and a, corresponding, generally, to the outside of t'he rounded portion of the draft-eye and of the ham e-loody, the latter recess extending across the die at right-anglesto the former, said bottom die also having deeper recesses,b c, at the point which is commonly called the neck,. where the draft eye and hame-body join, and also a recess, (1, formed in the edge of the semicircular recess or groove'for the hame-body. There is also formed on said bottom die two projections, 6, at the opposite sides of the first-named recess close to where the hame-body and draft eye join, the object of which will be herein after stated.

The top or upper die, Fig. 4, is provided with two recesses or cavities, a, corresponding in their contour with the projectionse on the lower die, and a recess, f, extending across the die, which, when the dies are broughtinto conjunction, will coincide with the groove (1' 1 in the lower die. which serves as a puneh'to form theclip-hole at the end of the draft-eye'as will be understood. The recess or groove f is also broadened and deepened, asatfflat the sides and ltalso has a projection, 9, 5

bottointhereof, which serves the purpose ofj6o j causing the metal to spread and ibrm'slight I bosses on the fiat surface of the hame-body,

thus increasing the amountofstock atthe welding-point, and thereby increasing the strength of the weld. The recess d at the sideor edge r of the other die is forthe same purpose, and also for the purpose of causing the stock to clinch around the rounded side of the harnebody to aid in holding the parts together while taking the welding heat. The projections ,e serve the several purposes of guides to facilitate the'laying of the draft-eye stockin posi 1 tion, to upset and strengthen the draft-eye at stock to form and clinch around the hame-' body at the neck, or where it joins said hamebody, to secure the requisite'amount of metal 86: i

at that point to form the finger, .anchor, or London draft-eye, as the case may 'be.

At the end of therece'ss for the draft-eye stock are formed additional recesses, hh,-which serve as guides to facilitate the placing of the 8 5 draft-eye stock in position in thedie prepara: tory to the forming and clinching process.

The bottom die of the welding-dies, Fig. 1

is provided with guides 70 and l to aid in lay ng and holding the hame and .draft-eye' t cesses m, formed alongthe edge of the bed. for the hamebody at each side of the space for the neck, the object of which is to secure in the proper position on the die, andwith re I a surplus of metal and increased strength at those points. A- recess, 0, is for the purpose of providing room forthe spread of themetal, so. that the dies will come close together and the flash will be as thin as possible after the welding,-.&c., is done. The guides k may beformed as a part of the die, as herein shown, or they may be a separoc' rate fixture attached thereto, as may be pre ferred.

The mode of operation is as follows: The hame-body is first laid in the die, Fig. 5, in the groove 61/ provided for it, cold. The drafteye stock is then brought to a red heat, and is laid in its position-via, the recess or cavity a in the diesaid piece being of suflicient dimensions to cover and fill the recess prepared for it, and also to extend across .the hamebody. Then the upper die is immediately brought down with sufficient force to drive the metal into the respective grooves and recesses hereinbefore described, to sink the cold hamebody into the heated draft-eye stock, and also to punch the clip-hole halfway through, oras far as the punch will make it. This operation imparts the general form to the draft-eye, upsets the metal at the proper points, punches the clip hole, and thoroughly clinches the draft-eye stock around or to the hame body, leaving a redundancy of metal at the points desired, for the purposes described. The parts thus joined are then put into the fire and brought to a welding heat, when the second set of dies are brought into use, the parts being laid flat side down on the bottom die, Fig. 1, the projection l and the guides k serving to hold the stock in its proper position, as will be understood. The top die is then brought down with sufiicient force to thoroughly weld and completely form and finish the draft-eye and hame-body, except a thin film or flash which may be left at the edges, and which is subsequently trimmed off with asuitable tool.

The mate or top die is provided with recesses A B, corresponding in shape and size with the. draft eye and hame-body, and with recesses K at the opposite ends of the recess B to receive the guide projections K of the mate die, as will be understood.

Having thus described the invention, what I claim as new isl. Dies for partially forming and clinching a draft'eye to ahame-body, consisting of a die having recesses or cavities a and a, corresponding substantially with the dimensions of a draft-eye and hame-body, a projection, e, at each side of the cavity a, near its junction with the cavity a, and recesses or cavities, as b c,

at the junction of the cavities e e, to receive the projections e on the opposite die, recesses ff, and a punch projection, 9, all being disposed and arranged to operate substantially as and for the purposes set forth.

2. Dies for welding a draft-eye to a hamebody, one of which is provided with a projec tion or punch, Z, to punch the hole for the trace-clip, arecess or cavity, 0, partially surrounding said punch, guide projections k at the opposite sides of said dies and recesses, and the other with recesses A B, corresponding in size and shape with thoseof the drafteye and hame-body, and with recesses K at the opposite ends of the recess B, all being disposed upon the face of said dies substantially as shown and described, for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 19th day of May, 1887.

WILLIAM H. WALKER.
